having fixed cylinders and reciprocating' TUnBI'Nn Appuation med :muy 2a,

To all whofm, it may concern.'

Be it known that I, LESTER L. BROWN, a citizen of the United States, residin at Houston, in the county of Harris and tate of Texas, have invented certain new and useful Improvements in a Turbine, of which the following is a specication.

This invention relates to new and useful improvements in a turbine and has more particular relation to a turbine of the internal combustion type. One object of the invention is to provide a rotary turbine equipped with cylinders which are -fixed in relation to each other and which revolve around a stationary crank shaft and which are impelled by the expansive force of an explosive fluid operating against vanes, carried by the revolvable cylinders. v Another object of the invention is to provide a turbine of the character. described sleeves therein which control the intake and exhaust of the motive Huid.

A further feature of the invention resides in the provision of cylinders of a novel construction which are separated into a compression and an explosion chamber,l and the reciprocating sleeves of which' control the intake of the motive fluid into the compression chamber and the delivery thereof from said compression chamber into the explosion chamber whereby the motive fluid is confined in the explosion chamber from which the force of the explosion is discharged against the impeller vanes, thereby imparting rotation to the turbine.

With the above and other objects in view the invention 'has particular relation to certain` novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 isa vertical sectional view taken on the line 1, 1 of Figure 2.

Figure '2 is. a transverse sectional view taken on the line 2, 2 of Figure 1, and

Figure 3 is a vertical sectional view taken on the line 3, 3 of Figure 2.A

' Referring now more particularly to thel drawings wherein like numerals of' reference designate similar parts in each of the figures, the numeral 1 designates a suitable framework,'which is shown in fragmentary form in Figure 2, and fixedagainst i920. Serna No. '399,010.

rotation in this frame-work there is a central intake pipe 2 whichterminates in a bearing pin 3, aligned with said pipe, and formed integrally with them there is an ec,- centric ywrist 4:.w Rotatably mounted upon the intake pipe 2 andthe bearing pin 3are I the clrcular end plates 5 and 6, which are spaced apart, and between these end plates there are the radiating cylinders 7. These cylinders" are vsecured in fixed position by means of the intervening arcuate webs 8,

formed integrally with said cylinders. The l outer end of each cylinder is closed' by means ofthe head' 9, and fitted within each cylinder there is a reciprocating sleeve 10. The outer end of each sleeve is closed by means of a disc 11', which fits snugly therein .and which is spaced from the corresponding head 9, thus forming an explosion chamber 12 between said head and disc. Each disc 11 is anchored to its corresponding head by. means of a 'centrally located neck 13, formed integrally with said head and disc,

and threaded through each head there is a suitable spark plug 14. Within each sleevel 10 there is a piston 15. Piston rods 16 are provided, the outer ends of these rods are pistons' 15 in the sleeves 10 which, as obvious, revolve with the cylinders.

Keyed upon the bearing pin 3, within the end plate 6, there is an eccentric 18 having a peripheral rib, and fitted around this eecentric there is a ring 19 having an internal groove provided to receive sald rib whereby the rin is held in position on the eccentric 18. T e sleeves 10 are connected to said ring through the instrumentality of the actuating links 20, which are pivoted at their inner ends to the ring, and at their outerends to said sleeves, and as the Iunitary structure, above described, revolves, the sleeves 10 fare, reciprocated back and forth in their respective cylinders. Each cylinder isprovided with an intake port 21, and each' sleeve is provided-with an intake port 22. Upon suction stroke of either piston 15 the corresponding sleeve moves inwardly, threugh the instnlleeetelity Qt.-

. has operated to move said sleevelou rthickness or the oo duid into the compression chber -Within said sleeve. Before ther compression lstroke of said piston has begun, the eccentric 1 8 twardly to close the intake 21. and thus confine the explosive fluid Within said compression chamber. rlihe motive fluid is admitted by suction .throughthe inlet pipe 2 into 'the chamber, enclosedbetweenA the end plates 5 and 6, and said duidis then admitted, as explained, into the compression chamber. Each sleeve 10 is also provided with an oblong port 23, somewhat. longer than the f-z, Ondlll 11, and upon compression'stroeof t e piston, the sleeve lOl has been moved outwardly into position so that the compreion chamber and explosion chamber are connected. through said port 23 andthe explosive duid is driven by said piston through said port 23into the combustion chamber and thereupon, prior to the explosion, the sleeve 10 is again moved inwardly, carrying the pont 23 out of connection with the explosion chamber and thereby closing said chamber.

. 'llhe eccentric 18 is so disposed relative to' s the end plate 6 and ope r the wrist pin d as tobring about this cycle or movement oit the sleeve 10 uniform succession with relation to the' movements or the pistons 15. Leading from each explosion chamber through the w of the cylinder and continuing through the end` -plate 6, are the discharge ports 2a, and upon its back stroke, the sleevelO uncovers these ports at the instant ortlie explosion and the explosive Huid is driven with great force through said ports 2li, lagainst the stationary vanes 25. l

llh'ese vanes are formed on the inner .face

of a Istationary annular casing 26, and are alately arranged' with respect to the 2 y rood `in.

' tegrally with theaannular support 28 laSr.

t is to be observed that the' pistons 15 and sleeves 10 of the f retive cylinders are timed to operate su thus -musing successive explosions tojoceur in the' respec. tive chambers 12, thus imparting to the mov- 'able impeller blades successive, impulses of the lesive 4duid anddrivingthe turbine at a continuous unirerotationi,
